SKAI® Benefits

The SKAI power electronic platform comprises highly integrated motor controllers which provide the ideal powertrain solution for mobile electric and hybrid applications. Power densities of up to 25 kVA / liter bring about notable size reductions compared with other existing standard motor controller products. The systems are designed to operate with supply voltages of 24V to 800V and with output power ratings of up to 300 kVA. The IGBT-based SKAI 2 HV motor controller operates on sintered, 100% solder-free 600V or 1200V power semiconductors and it features polypropylene film DC-link capacitors. The MOS-based SKAI 3 LV uses established SKiiP technology with a very low-inductance connection to the DC-link capacitors, driver electronics, current, voltage and temperature sensors. It is integrated into a waterproof IP66 enclosure. The compact products can withstand high vibration amplitudes of up to 10g rms. SKAIware motor control software adds to the system function and finishes off this tried-and-tested package for the SKAI 2 HV nicely. SEMIKRON provides engineering services to support customers with the integration of SKAI systems. Other available services include, for instance, lifetime estimation, field application support, individual parameterization of motor control software, and others.
